Indoor thermal environment monitoring has been done in 20 residential buildings of Liege city followed by questionnaire based comfort survey amongst the occupants of 85 houses in order to record their preference and expectations about indoor thermal environment in winter and spring season. It is found from the analysis that change of glazing has a minimum or even sometimes an adverse effect on the existing indoor environment due to the absence of proper insulation of the rest of the building envelope. It is observed that in winter there is a sudden drop in indoor temperature and also overheating in summer. This is due to unplanned installation of glazing which actually increases the fenestration area ratio leading to higher indoor temperature fluctuation and causes discomfort. It is also important that the occupant?s preference and expectations as well as overall assessment of indoor environment needs to be consider towards energy efficiency improvement.

An optimal design is taken on the external respiration double skin facade (DSF) of a office building in Wuhan. The indoor thermal environment of the office units in the building have been simulated by taken computational fluid dynamics (CFD) method, and then the paper analyzes the indoor temperature changes under the condition that the internal airflow status of the DSF for natural ventilation, without shade, vents closed and other cases, discusses the influences of different inner glazed skin’s thermal properties, DSF for active ventilation and different wind speed on indoor thermal environment, according to the simulation results we obtain parameters of relevant optimal design.

This paper reviewed related research works and developments on the traditional architectural element “mashrabiya” focusing on its history, design and structure, typology, and functions in hot climates. Moreover, the paper assessed the effect of the traditional mashrabiya on the indoor thermal environment and thermal comfort in a selected case study building. For this purpose, two similar rooms were investigated in a selected historic building with abundant mashrabiyas located in the Makkah Region, specifically in Old Jeddah, Saudi Arabia. The field tests were conducted during a typical hot summer month with two different configurations. The study demonstrated that opening the mashrabiya allowed more airflow into the room during the day and reduced the indoor temperature by up to 2.4 °C as compared to the closed mashrabiya. Besides, the building envelope played an important role in preventing the high fluctuation of the indoor air temperature, where the fluctuation of the rooms air temperature ranged between 2.1 °C and 4.2 °C compared to the outdoor temperature which recorded a fluctuation between 9.4 °C and 16 °C. The data presented here can be used for the future development of the mashrabiya concept and the potential incorporation with passive cooling methods to improve its design according to the requirements of modern buildings in hot climates. Moreover, further studies and tests on mashrabiyas under different climatic conditions are required. Also, the different strategies or materials can be incorporated with mashrabiyas in order to improve its thermal performance.

To compare the indoor thermal environment under different building envelope constructions, a Matlab-based tool was presented for building envelope performance simulation. An application study of two cases illustrates energy efficient buildings can provide more suitable indoor environment than non-energy efficient buildings in cold winter and hot summer. In conclusion, this paper provides a new and fast way for the prediction of indoor thermal environment.
